1 Scope

GB/T 42474.5-2023 defines the link between the vehicle and the control room for road transport of explosive hazardous chemicals. A truck carrying explosives is tracked continuously - position, speed, driver behaviour, the state of the load and of the vehicle's safety equipment - because if something goes wrong, the response depends on knowing where the vehicle is and what it is carrying before anyone arrives. That tracking is only as good as the interface between the on-board device and the communication centre, and unless the interface is specified, every equipment supplier invents its own and a regional authority ends up unable to monitor vehicles from another province. This part specifies the wireless data communication interface for data exchange between the on-board device and the communication centre, including the composition of the data interface, the message structures and the communication procedures. It is Part 5 of the GB/T 42474 series, the part that makes the fleet visible. Under ICS 13.320 and CCS A91, it is written for the manufacturers of on-board monitoring terminals, for the platform operators running the communication centres, and for the transport enterprises and safety regulators who depend on the data arriving intact.

This document specifies the wireless data transmission between the vehicle-mounted device and the communication center in the vehicle transportation safety monitoring system for explosive hazardous chemicals Communication interface for data exchange, including data interface composition and communication method, general requirements, communication protocol classification and data format: This document is applicable to the application of various vehicle-mounted devices and communication centers of the safety monitoring system for automobile transportation of explosive hazardous chemicals: Other dangers The safety monitoring system for motor vehicle transportation of dangerous goods can be used as a reference:
